2000 Lincoln Town Car Q&A
2000 Lincoln Town Car Question: Brake light switch harness melting
Thank you for your time. I am a professional technician in Texas and have had a continuing issue with the brake light switch harness melting on this car for a year now. I have replace the switch, harness, and shift interlock solenoid with motorcraft parts and still had the melting issue. I then found a TSB in our software nuber "02-13-6". This states that the harness be replace with kit #2W1Z-14A411-AAA". I ordered the harness from Ford and installed per the bulletin, which in fact states "the harness is polarity sensitive" (I still can't understand this)yet the harness has already started to melt after one week. My local ford dealer has been of no help and other freinds in the industry have not had an issue like this one. Any thoughts from you would be of great help. Starting to get embarrassing.

Hey Gary, Welcome to RepairPal, good question, and great info. I'm looking at the wiring diagram, and I'm not quite clear on which wire(s) is melting. I see the LG/RD wire from the fuse to the switch, then the LG wire to the Central Junction box. Are these connected correctly (Polarity issue referred to in the TSB?) Is it one or both of these wires? What is the current draw when activating the brake lights? - Bret Bodas
You need to wire in a relay....http://www.lincolnsonline.com/tech/00114.html - JimMorrison
